Title: Improvements in apparatus for braking a sequence of vehicles forming a train
IPC: B60T8/32
Filed: 1947-05-30
Abstract: 634,208. Automatically regulating train brakes. TECALEMIT SOC. ANON. May 30, 1947, No. 14409. Convention date, July 2, 1946. [Class 103 (i)] The braking system on a train is automatically adjusted very nearly to the wheel locking condition by means of device fitted to one of the vehicles, which acts in such a way that an increase in the intensity of braking due to an increase of adhesion is only permitted when the last axle of the train has passed beyond the initial point where the said increase of adhesion occurred. A pulley 3 secured to one axle 1 of a vehicle (not shown) is coupled by belt to a pulley 3 1 , of slightly larger diameter, freely rotatable on another axle 2 of the same vehicle, so that without any wheel slip the pulley 3 1  would tend to rotate slowly on axle 2. This rotation, however, is prevented by the engagement of a roller 6 secured on arm 5 integral with pulley 3 1 , in a notch in a collar 7 axially slidable on axle 2. A bell-crank lever 9 pivoted at 10 has one end guided in a groove 12 formed in the collar 7 and the other end coupled by a rod 13 to a lever 14 pivoted at 15 and under the action of a spring 18. Thus the collar 7 is forced to the left by the action of the roller 6 until an equilibrium condition is reached at which it is balanced by the force in the spring 18, the deflection of the end 17 of the lever 14 being then a measure of the adhesion of the wheels on the track. A regulating device, Fig. 5, comprises a central member 21 that is made to rotate within a casing, by means of a pinion 30 coupled to one of the vehicle's axles, through one of revolution during the time train has travelled its own length. A series of rods 22, equally spaced angularly between the member 21 and its casing, are free to move upwards but locked from downward movement by balls 23. The end 17 of lever 14, the position of which is a measure of the wheel adhesion, by pressing against a shoe 31, adjusts in succession the height of each of the rods 22 as they move round with member 21. The tops of the rods 22 press against a cap 25 urged downwardly by a spring 27, the position of the cap 25 raising or lowering a lever 20 which adjusts the pressure in the trains main braking system accordingly.

IPC: B02C2/00
Filed: 1958-05-06
Abstract: 888,007. Gyratory crushers &c. NORDBERG MANUFACTURING CO. May 6, 1958 [May 24, 1957; June 12, 1957], No. 14444/58. Class 59. A machine part or component for use in gyratory crushers, grinders and like machines comprises a wear-taking metal portion and a backing layer consisting of or comprising a thermo-setting synthetic plastic in close contact with the metal portion for cushioning the metal portion against stresses applied to it. Preferably, the backing layer comprises an epoxy resin. As shown, the outer conical surface of a bowl liner 14 and the inner conical surface of a mantle 16 are partly relieved so as to form annular cavities 26, 28 between the liners and their crushing elements 10, 12, which cavities are filled with the epoxy resin to form backing layers 30, 32. In a modification, the backing layers extend from the top to the bottom of the liners. The metal portion may have a thickness of at least three inches while the backing layer has a thickness between # inch and ¢ inch. The backing layers are formed by pouring the epoxy resin into the cavities 26, 28 and to ensure that the resin and its curing agent are properly mixed, they may be of different colours or means provided to indicate when the mixture has reached a predetermined temperature. Alternatively, the backing layers may be formed separately or applied to the liners before these are fitted on the crusher. The backing material may include a filler e.g. sand, silica, powdered aluminium, fibre glass particles, bentonite and other clays, synthetic resins, asbestos and talc. To reduce the viscosity of the epoxy resin, the backing layer may include butyl glycidyl, styrene oxide, phenol glycidyl, ether or xylene.
